To all whom it may concern:

Be it known that I, AL'rHEa Minter,

citizen of Newfoundland, and a resident of the city of New York, boroughof Manhattan, in the county of New York and State of New York, haveinvented certaiiriieimand useful Improvements inCalendars, of which thefollowing is a specification.

The object of this inventionis to provide a convenient reminder of thecurrent month day and week-day by means of a device which may beassociated with a watch-cover or other convenient support. Afurtherobject is to provide this device in a structure having few partsand in which the monthday and week-day may be displayed in relativelylarge characers.

In the accompanying sheet of drawings which forms a part of thisapplication,

Figure 1 is a view of the back of a watch, the cover of which carries adevice embodying my invention;

Fig. 2 is an edge View of the watch, the back cover and calendar disksbeing in section- Fig. 3 is a view of the month-day disk;

Fig. 1 isa view of the week-clay disk;

Fig. 5 is a View of a modified form of month-day disk; and

Fig. 6 is a view of a modified form of week-day disk.

The device embodying my invention is shown associated with the backcover a; of a watch. Anionth-day disk I) carries on its.

month. This disk may be of celluloid, aluminum, or any other suitablematerial, and as shown it may be reinforced at the center by a disk 0 offine light colored silk, linen or-muslin, and may be properly backed toprevent scratching. The disk is carried by a spindle cl upon which it issuitably and removably mounted, and this spindle is journaled in thecover and has a milled head 6.

Concentric with the month-day disk and superimposed thereon is aweek-day disk 7 loosely mounted on the spindle, but having sufficientfriction therewith to prevent undesired rotation in respect thereto.This disk bears'the names of the days of the week as ordinarilyabbreviated, and is provided with teeth 9 g on its periphery.

In the cover is an opening h through which the name of "week-dayjmay beseen, and an reflies Wliih ieiu aide e s 5 t assoclated dig ts and .nomore forming the designationof an onth-day o be seen. This opening also,afl ordsaccess to the teeth of the weekday to permit thelatter to be tbyinse tin t e P n of a r m Two arrangements of digits forrepresenting'the days of the monthare shown, In Fig. 3 is shown anarrangement forsetting to successive days by right-hand or clockwiserotation of the spindle knob except for three: transpositions, whereitis necessary to turn back for 12 after 11, for 14 after 13, and for 23after 22. If all the 31 days of the month were separately provided foron the disk, then with the necessary spacing each digit could be givenan angular space on the disk amounting to one-sixty-second part of theperiphery. But it will be seen that by the rearranging shown each digitcan occupy o1'1e-forty-eighth partof the periphery, and can therefore beproportionately larger. This gain in the main results from theelimination of separate digits for representing the month-days from 1 to9 inclusive, and suitably inserting spaces after the numerals 21 to 29inclusive so that digits 1 to 9 inclusive which are associated withthese numerals may be displayed singly through the opening in the cover.Further gain results from having a digit 1 associated with the numeral12 to provide for the numeral 11, in having a digit 2 associated withthe numeral 23 to provide for the numeral 22 and in having the digit 3of the numeral 13 associated with th digit 1 of the numeral 14: toprovide the numeral 31.

In Fig. 5, is shown an arrangement of the digits and numerals for settinto successive days by left hand or counter c ockwise rotation. With thisarrangement the transpositions required in the case of clockwiserotation are eliminated. 1

For convenient setting of the week-day disk, the week-days should readthe opposite way around from the month-days, the week day disk of Fig. 4being used with the month-day disk of Fig. 3, and the weekday disk ofFig. 6 being used with the month-day disk of Fig. 5. However, owing toth fact that the designations on one of the two associated disks is readabove the center and the other below the center, the direction ofrotation of both disks in consecutive setting is the same.

Sp ecifica'ti on of Letters Patent. Patgntgd 25, 191$,

The foregoing detailed description has been given for clearness ofunderstandm U and no undue limitation should be'deduced therefrom, butthe appended claims should be by Letters Patent of theUn'i'ted States,is '1. The combination ofa month-day disk bearing digits forrepresenting the days'o'f the month, the digits'being in such Sequenceand with such spacing that one set of digits for representing'the' monthdays from 1 to 9 inclusive also Will-form parts of two digit mo'nth-dadesignations, a cover having-an opening t' rough which two consecutivedigits may be seen, and means for setting the disk, substantially asdescribed.

4 2. The combination of amonth-day-disk new, and desire to securebearing digits for representing the days of the month, the digits beingin such sequence and nude such spacing that one set of digits for,representing the month-days from 1 to 79 inclusive also will iorm partsof two digit numeral 31, a over having an opening through which twoconsecutive digits may be seen, and means for setting the disk,substantially as described.
